Introduction

This is a build script to create, and optionally install, libtorrent.so statically linked against openssl, libtorrent 1.1, 1.2 or 2.0 and boost-python. wolfssl is available as an alternative to openssl when using libtorrent v2 onwards.

This makes setting up Deluge + libtorrent + ltconfig 2 an automated and reasonably quick installation by copy and pasting a few commands.

Based on these docs:

Build script usage

• The script will install the required dependencies when run as a root or using a docker image.
• You can setup the build environment as root and then use the build function as a local user.
• The script is designed to work with a docker image/container and works with docker rootless

There are three stages to the script depending on what requirements it detects.

• It will update the system and require a reboot to proceed, if required.
• If no reboot is required it will continue to install the build environment dependencies and exit unless a module was passed as an argument.
• If the run using a module argument like all it will start building libtorrent-python-binding or the specified module using python3.

Help options

The script tries to be automated and helpful but here are the help options to guide you.

Here are a list of available options

 Use: -c  or --crypto            Help: -h-c  or --help-crypto
 Use: -n  or --no-delete         Help: -h-n  or --help-no-delete
 Use: -lm or --libtorrent-master Help: -h-lm or --help-libtorrent-master
 Use: -lt or --libtorrent-tag    Help: -h-lt or --help-libtorrent-tag
 Use: -p  or --proxy             Help: -h-p  or --help-proxy
 Use: -tb or --test-build        Help: -h-tb or --help-test-build
 Use: -s  or --scope             Help: -h-s  or --help-scope

Module specific help - flags are used with the modules listed here.

Use: all or module-name         Usage: ~/libtorrent-python.bash all

Here are a list of dependency specific modules

 update --------- update host - apt/apk update
 install -------- Install dependencies
 bootstrap ------ update and install combined
 install_deluge - pip install deluge

Here are a list of build specific modules

 all ---------- Install all modules - openssl boost libtorrent
 openssl ------ Install the openssl module (default)
 wolfssl ------ Install the wolf module (Libtorrent v2 only)
 boost -------- Download, extract and bootstrap the boost build files
 libtorrent --- Build the libtorrent python binding

Installation unified

libtorrent-python.bash us works on modern Alpine or Debian based hosts.

curl -sLO https://raw.githubusercontent.com/userdocs/python-libtorrent-binding/refs/heads/master/libtorrent-python.bash
chmod +x libtorrent-python.bash
./libtorrent-python.bash

There are two ways to use the script

• With a docker image for the relevant platform.
• Run directly on the system where you want to build the binding.

Debian or Ubuntu

Using Docker

• Port 8112 for deluge installation.
• Built to $HOME/bindings

All in one Ubuntu/Debian docker command

Note: This command can be configured using flags top provide a specific outcome. Change ubuntu:20.04 to debian:stable to use Debian.

docker run -it -p 8112:8112 -v $HOME/bindings:/root ubuntu:latest /bin/bash -c 'cd && apt-get update && apt-get install -y curl git && curl -sL git.io/gplibtorrent | bash -s all && bash'

Optional - Setup Ubuntu/Debian Docker fist

Optionally you could create and configure the docker first and then use the script from within the container.

docker run -it -p 8112:8112 -v $HOME/bindings:/root ubuntu:latest /bin/bash -c 'cd && apt-get update && apt-get install -y curl git && bash'

Optional - Download and run inside Ubuntu/Debian docker

Now you can call commands from within the docker container.

curl -sL git.io/gplibtorrent | bash -s all

Note: You can modify this part bash -s all in either method to customise the behaviour of the command. Refer to the help section above.

Using glibc script

Note: You can do this from within a docker container as well.

wget -qO ~/libtorrent-python-binding.sh https://git.io/gplibtorrent
chmod 700 ~/libtorrent-python-binding.sh
~/libtorrent-python-binding.sh

Alpine

Using Docker

• Port 8112 for deluge installation.
• Built to $HOME/bindings

All in one Alpine docker command

Note: This command can be configured using flags top provide a specific outcome.

docker run -it -p 8112:8112 -v $HOME/bindings:/root alpine:latest /bin/ash -c 'cd && apk update && apk add bash curl git && curl -sL git.io/mplibtorrent | bash -s all && ash'

Optional - Setup Alpine Docker fist

Optionally you could create and configure the docker first and then use the script from within the container.

docker run -it -p 8112:8112 -v $HOME/bindings:/root alpine:latest /bin/ash -c 'cd && apk update && apk add bash curl git && ash'

Optional - Download and run inside Alpine docker

Now you can call commands from within the docker container.

curl -sL git.io/mplibtorrent | bash -s all

Note: You can modify this part bash -s all in either method to customise the behaviour of the command. Refer to the help section above.

Using musl script

Note: You can do this from within a docker container as well.

wget -qO ~/libtorrent-python-binding.sh https://git.io/mplibtorrent
chmod 700 ~/libtorrent-python-binding.sh
~/libtorrent-python-binding.sh

Some configuration examples

all - Install defaults openssl > boost > libtorrent using v1.2.* latest version

all pv 2 -lt libtorrent-1_1_14 - Install openssl > boost > libtorrent using the release 1.1.14 built with python2

all -lm - Install defaults openssl > boost > libtorrent RC_1_2 main branch

all -lt RC_2_0 - Install defaults openssl > boost > libtorrent using the RC_2_0 main branch

all pv 2 -lt RC_2_0 - Install defaults openssl > boost > libtorrent using the RC_2_0 main branch built python2

all -c wolfssl -lt v2.0.1 - Install wolfssl > boost > libtorrent using the release v2.0.1 built with python3

all pv 2 -c wolfssl -lt v2.0.1 - Install wolfssl > boost > libtorrent using the release v2.0.1 built with python2

Post build

Once the script is finished the required files will be built

~/libtorrent-python/completed

You can install deluge by using the command:

~/libtorrent-python-binding.sh install

It will install to the ~/.local directory of the user running the script.

Note: This script does not attempt to configure deluge.
